Bajaj finace - Bajaj finance AMC fraud

I am a customer of flexi loan of Bajaj finance. I have taken this flexi loan account number P***PSP******* from Bajaj finance last year. Issue came to my notice when my account was approached to deduct an AMC. This flexi loan was offered to me without sharing such valuable information of additional charges to be levied on the account to just keep the account open and continued. I have used the flexi loan on many occasions pervious year and timely paid all interest related expenses alongside widrawn amount. My account won't be seen with decline of payment. But surprisingly This AMC was not shared with me at the time of sharing the loan amount. It was actually kept hidden which suggests fraudulent intentions of the sales team or executive involved in dealing. Now I have lost my faith in Bajaj finance team completely since hiding such valuable information is strictly not acceptable.
